Platte River Caddisfly
A caddisfly found in only a handful of Nebraska channels completes part of its aquatic life while its wetland is seasonally dry.

Larvae build cases from vegetation, develop in shallow water, then enter moist soil or litter as channels recede. That unusual timing links the species to a precise cycle of inundation, drying, groundwater, and intact vegetation.
This is a conservation-learning species, not a collecting target. Observe central Platte wetlands from public routes, never disturb drying channel beds, and report credible photographs to specialists without broadcasting sensitive locations.
- Best clue
- Small brown caddisfly whose aquatic larva carries a curved case of plant fragments
- Habitat
- shallow vegetated side channels and temporary wetlands near the central Platte River
- Regional status
- Extremely localized central-Platte insect
Quick guide
- First decision
- Long threadlike antennae
- Context check
- Mottled tent-like wings; context: shallow vegetated side channels and temporary wetlands near the central Platte River
Field decisions for Platte River Caddisfly
- Establish the whole form
- Begin with Long threadlike antennae.
- Separate the nearest alternative
- Confirm Mottled tent-like wings before settling on the identification.
- Add ecological context
- Shallow vegetated side channels and temporary wetlands near the central Platte River; adults chiefly September–October.
- Leave the evidence intact
- Do not reposition, collect, bait, pursue, or clear vegetation around Platte River Caddisfly.
Good to know
The strongest Platte River Caddisfly record preserves the distinction between “Long threadlike antennae” and “Mottled tent-like wings” while also showing the surrounding habitat.
Notice these
- Long threadlike antennae
- Mottled tent-like wings
